To all whom t may concern;k

Be it known that I', JOHNA MCNEIL, a citizen of the United States ofv America, and resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Flushing- Nozzles, of which the following is a specification.

An object of my invention is to produce an improved iushing nozzle for troughs, in which means are provided for varying the discharge of water from the nozzle in accordance with the pressure of water flowing through the nozzle, whereby the water will be prevented from splashing.

This and other objects are attained in the fiushing nozzle described in the following specification and illustrated inthe accompanying drawings, in which:

Figure 1 is a fragmental sectional elevation of the upper end of a trough having a flushing nozzle embodying my invention attached thereto.

Fig. 2 is a side elevation of the nozzle disclosed in Fig. 1, upon an enlarged scale.

Fig. 3 is a sectional view of my improved nozzle.

Fig. 4 is a transverse sectional view taken on the line 4-1 of Fig. 2.

My `improved flushing nozzle consists of a body 5 having its upper end provided with screw threads 6 adapted to be connected with a pipe conducting the water to the nozzle, and having at its lower end a cover 7, a portion 8 of the cover being inclined and having a slot 9 located between it and the body portion 5. The slot is semicircular, extending from one side to the opposite side of the inclined portion 8 of the cover 7. Opposite the slot 9 is formed a hollow bearing lug 10 carrying a journal pin 11 upon which is mounted pivotally a discharge regulating plate 12 extending over the cover 7 and having an enlarged front portion 13 adapted to occupy the slot 9. This enlarged portion 13 forms the deflector against which the water passing through the body portion 5 is adapted to impinge so as to Cause it to spread into fan-like shape in passing through the slot 9. Opposite de; fleeting portion 13 of plate 12 is formed a lug 14 adapted to occupy bearing lug 10 and mounted upon journal pin 11. The purpose of pivotally mounting the plate in this manner is to permit vitto be raised or lowered to change the degree of opening of the slot 9 through which the water may pass. In

order to bring the plate to these adjusted positions I have provided a set screw 15 eX- tending through the cover 7 and bearing against the end surface of the plate. 12. Surrounding set screw 15 is an annular flange 16 which prevents the set screw being tampered with by necessitating the use of a tool of correct size tov operate the screw to bring the plate to its adjusted positions.

As the water passes through the body portion 5 and comes into engagement with the enlarged portion 13 of plate 12, it spreads and passes through the slot 9 in fan-like formation. Because of the inclination of portion 8 of the cover and portion 13 of the plate, together with the inclination of the slot, the sheet of water is projected down-V wardly at an angle. This engages the walls of the troughat an angle thereto and causes the water to flow down these walls without splashing therefrom. Should the water pressure be high, the plate 12 is dropped so as to present a wide opening in the slot through which the water will pass in suiiicient volume to prevent its squirting there# from. Should the water pressure be low the plate is raised, by adjusting set screw 15, until slot 9 has an opening sufliciently narrow to spread the small quantity of water passing therethrough into a fan-like stream. Having been spread into this fan-like formation, the water issues from the nozzle inl a gentle stream and engaging the walls of the trough at an angle thereto, flows over them without splashing.

In nozzles heretofore employed, the slot through which the water issued, was of uniform width, no means'being provided to vary the space through which the water could pass. This was objectionable in that with a high water pressure the water was projected through the slot with a velocity such as to cause it to be squirted therefrom and to splash after having engaged the walls of the trough. In low water pressure the uniform opening of such nozzles prevented the stream being spread sufficiently and from being projected against the walls of the trough, therefore causing it to fall to the bottom of the trough and to splash. It will thus be seen that in my improved flush- Patented J une 1, 1920.

ing nozzle construction l have overcome ployed.

Having thus described my invention, what IV claim is: Y

A flushing nozzle comprising a body having a bottom closing its lower end, e; portion of the bottom being inclined downwardly with relation to the other portion and having a slot formed in the body above the bottom and inclined downwardly with the inclined portion of the bottom, a plate pivotally mounted upon the body and having a downwardly inclined portion extending into and beyond the slot and adapted to engage 15 the inclined portion of the bottom, and a set screw mounted in and passing through the bottom andadapted to engageI the plete to move the plate from the bottom to the top of the slot to regulate the discharge of 20 i' water therethrough. 1 In testimony whereof I have hereunto subscribed my name this 27th day of March, i
